I found a discussion sometime ago about de Plaiz by Chris Phillips. I am specifically interested in their lands in Sussex held of the de Warrennes. Richard de Plaiz, son of Hugh and heir of the Montfichets, died 53 Henry III (1269). His widow Isabel was alive in 1284. He held Iford and the advowson of Worth (Orde) Sussex. Osbert de Cailly who married Emma Tatteshale sold rent in Wivelsfield (Wyvelesfelde), Worth, Iford, Mitching, Ovingdean and Wychcenden, Sussex, for £90 with the service of John de la Byse in those places, namely 1 knight’s fee to Walter de Bersted who evidently defaulted. By some means, John de la Bise acquires Iford and Worth. Does anyone know who Isabel was? Thanks in advance, Pat
